Oh, indeed... I definitely enjoy (at least a fair amount of) Hammer Horror! There are large amounts I've not seen, and some of the later pieces were... debatable, shall we say?
But at their best, they were quite wonderful; and (not speaking just of the blood) they made excellent use of color; they're very rich films visually.
Something I'd like to find out more about are the films put out by Amicus, as well; those don't get much mention, and they, too, had some very good entries in the realm of cinematic horror....
